I used to wear heels when I was younger- but I suppose 3 inch may have been the highest. There simply have not been shoes higher than 4 in then. Today I wear 1-1,5 in at the max and most of the days I am wearing flat ballerinas in the office and if we ever should see summer again ( we have weeks of predominant rain now) I'll be wearing leather flipflops in my time off.
I own 2 pair of sneakers- red leather Adidas that are about 10 years old and black suede pumas that are about 5 years old
